1 answer:
Answer:
The interest rate is 4% per annum.
Step-by-step explanation:
Let the interest rate that I am getting is r% per annum.
So, my $5000 investment becomes $6200 after getting r% simple interest for 6 years.
So, from formula of simple interest we can write
⇒
⇒
⇒ r = 4%
Therefore, the interest rate is 4% per annum. (Answer)

14. (2x - 1)(x + 7) = 0
Using the zero factor property, we know that either the first or second terms (or both) must be equal to 0 if their product is 0. We can set each term equal to 0 to find the solutions:
2x - 1 = 0
2x = 1
x = 1/2
x + 7 = 0
x = -7
15.
To solve this equation, you first need to set it equal to 0:
Next, it can be factored:
Finally, we can solve just like we did above:
x + 5 = 0
x = -5
x - 2 = 0
x = 2
16.
First, you can simplify by dividing each side by 4:
Now, set the equation equal to 0:
Next, factor:
Finally, find the solutions:
x + 5 = 0
x = -5
x - 5 = 0
x = 5
